Any 2 stoke motor relies on fuel/oil mix for lubrication. If you are running a motor at the top end of it's rev range then the fuel carrying the lubricant is especially important. When you shut the throttle the sullpy of fuel carrying the vital lubricant is no longer there hence the practice of choking motors at the end of the straight was born, initially in the late 60's & early 70's where the motors of the day were so highly strung and on the limit of seizure anyway it became a vital skill to master.
Many of the current engines using modern lubricants will most likely survive without choking but that depends on how lean the motor is being run and the state of tune.
This highlights the low stess level for a modern Max motor which invariably survive such abuse withot choking week in week out.
